The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

JEREZEM FEGLEY, NP appears in the CMS NPPES registry as a Family Nurse Practitioner provider holding NP credentials at 950 CAMPBELL AVE, WEST HAVEN, CT, 06516, with a listed phone of (203) 932-5711. NPI 1700412111 was issued on 03/17/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what FEGLEY most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 145 prescription claims written by this provider, covering 61 Medicare beneficiaries and totaling roughly $18K in drug spend, split 10% brand-name and 90% generic by claim count.

Family Nurse Practitioner is a high-volume specialty nationwide, with 209,817 enrolled providers across 56 states and an average of 1,222 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
